In the present work nanozeolite Y was prepared from nanosilica powder extracted from rice husks ash by sol–gel method as a green biosource (NZ). Melamine formaldehyde resin (MF) and melamine formaldehyde/nanozeolite Y (MFZ) particles were prepared at pH 9 and 110 °C. NZ, MF, and MFZ were characterized using TGA, SEM, XRD, nitrogen adsorption, pH_PZC, and FTIR. Melamine formaldehyde/nanozeolite Y exhibited an advanced textural structure with surface area of 1035.6 m²/g and abundance of chemical functional groups. Lead ions adsorption was investigated under different application conditions considering thermodynamic and kinetics studies. The maximum adsorption capacity (q_m, mg/g) was confirmed by MFZ and found to be 180.8 after 60 min of equilibrium time at pH6, 1.0 g/L as adsorbent dosage, and at 40 °C. Lead (II) adsorption onto solid adsorbents fitted with Langmuir adsorption, pseudo-second order, Elovich kinetic, and Vant Hoff’s models. Thermodynamic investigations showed that lead adsorption by all the adsorbents are spontaneous and endothermic.

在目前的工作中，Y沸石是用溶胶-凝胶法从稻壳灰中提取的纳米二氧化硅粉作为绿色生物源（NZ）制备的。在pH 9和110°C下制备三聚氰胺甲醛树脂（MF）和三聚氰胺甲醛/纳米沸石Y（MFZ）颗粒。使用TGA，SEM，XRD，氮吸附，pH _PZC和FTIR对NZ，MF和MFZ进行表征。三聚氰胺甲醛/纳米沸石Y表现出先进的组织结构，表面积为1035.6 m ² / g，具有大量的化学官能团。考虑到热力学和动力学研究，在不同的应用条件下研究了铅离子的吸附。最大吸附量（q_米，由MFZ确认，在平衡时间60分钟（pH6），1.0 g / L作为吸附剂剂量和40°C平衡时间60分钟后为180.8。铅（II）吸附在符合Langmuir吸附，拟二级，Elovich动力学和Vant Hoff模型的固体吸附剂上。热力学研究表明，所有吸附剂对铅的吸附都是自发的并且是吸热的。
